Benefits of technology
The patent is about a new display device and a way to make it. The invention stops problems like poor image quality and color mixing that can happen when a black matrix and color filter don't match perfectly.
Problems solved by technology
Furthermore, the organic light emitting display devices are driven with a low direct current (DC) voltage, have a fast response time, and are low in manufacturing cost.
In this case, however, due to an error of the photolithography process, an aperture ratio is reduced, and mixing of colors occurs.

Abstract
Disclosed are a display device and a method of manufacturing the same, which prevent a reduction in an aperture ratio and occurrence of color mixing caused by a process error of a black matrix and a color filter. The display device includes a plurality of color filters, an inorganic layer covering the plurality of color filters, and a black matrix disposed on the inorganic layer between the plurality of color filters.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of Republic of Korea Patent Application No. 10-2016-0111872 filed on Aug. 31, 2016 and Republic of Korea Patent Application No. 10-2016-0139009 filed on Oct. 25, 2016, both of which are hereby incorporated by reference as if fully set forth herein.BACKGROUNDField[0002]The present disclosure relates to a display device and a method of manufacturing the same.Discussion of the Related Art[0003]With the advancement of information-oriented society, various requirements for display devices for displaying an image are increasing. Therefore, various display devices such as liquid crystal display (LCD) devices, plasma display panel (PDP) devices, organic light emitting display devices, etc. are being used recently.[0004]As a type of display device, organic light emitting display devices are self-emitting display devices and have better viewing angle and contrast ratio than LCD devices. Also, since the organic li...
